EVALUATION OF WELDED DEFORMED WIRE FABRIC REINFORCEMENT IN MACHINE-MADE CONCRETE PIPE

THE STRUCTURAL BEHAVIOR OF MACHINE-MADE CONCRETE PIPE REINFORCED WITH WELDED DEFORMED WIRE FABRIC WAS EVALUATED AND THE VALIDITY OF PREVIOUSLY DEVELOPED DESIGN METHODS FOR THIS KIND OF PIPE WAS DETERMINED. MACHINE-MADE PIPE EXHIBITED IN TESTS GREATER 0.01-INCH CRACK STRENGTH AND UL- TIMATE STRENGTH VARIABILITY THAN DID PREVIOUSLY TESTED CAST PIPE. GIVEN THIS VARIABILITY, THE DESIGN FORMULAS PREVIOUSLY DEVELOPED FOR 0.01-INCH CRACK STRENGTH AND ULTIMATE FLEXURAL STRENGTH OF CAST PIPE CAN BE TAKEN TO APPLY TO MACHINE-MADE PIPE. THE DESIGN FORMULA FOR ULTIMATE DIAGONAL TENSION STRENGTH MAY ALSO BE APPLIED TO MACHINE-MADE PIPE, BUT WITH A LARGER SAFETY FACTOR AND WITH CERTAIN MODIFICATIONS OF PROVISIONS TENTATIVELY SUGGESTED IN EARLIER WORK. COMPARISON OF TEST RESULTS ON COMPANION PIPE INDICATES THAT DEFORMED WIRE FABRIC OFFERS HIGHER 0.01-INCH CRACK STRENGTH THAN SMOOTH WIRE FABRIC. FOR PIPE MADE BY THE PACKERHEAD PROCESS, THE DEGREES OF IMPROVEMENT IS EVEN GREATER THAN WAS FOUND PREVIOUSLY FOR CAST PIPE. /AUTHOR/
